Since the TXOne StellarOne VM and its clones are technically the same including settings and configuration there is no need to do any extra steps or procedures. You can just simply turn on the clone TXOne StellarOne VM the moment the main TXOne StellarOne goes down and it should take over without any problems.

 
Ensure cloned and original StellarOne are not running at the same time as they have the same IP Address
